Analysis of Drugs & Drug Metabolites

Porvair Sciences Ltd. has released an application note describing the operational benefits of using their innovative Microlute Solid Phase Extraction (SPE) ­system for analysis of drugs and drug metabolites in biological fluids. Based upon independent customer data the application note describes how the SPE, prime wash and elution volumes stages of sample preparation are significantly reduced using the Microlute allowing faster sample processing and increased method sensitivity. The application note further shows that the individual well capacity of the low sorbent mass phases used in the Microlute are more than sufficient for the needs of analysing the typically low levels of pharmaceutical drug metabolites found in biological fluids. Developed in conjunction with a leading pharmaceutical company the Microlute has become the benchmark for high throughput sample preparation across a range of ­applications.
